Drag concrete floor from sand, the Department can bridge cement floor from sand

 Concrete floor cracks on asphalt concrete pavement has a length more than 30 meters long longitudinal crack, how to deal with the warehouse concrete floor from sand, transverse cracks how to deal with pit-like how to deal with Henan Meeting to bridge the professional pavement / bridge repair production of new materials and comprehensive solution tactic program service integrator, is road repair quick passage of an industry leader! cracks in the concrete floor dusting, first determine the level of the concrete floor cracks appear, 1, if the width is less than 1mm, can use Henan Road and Bridge Department of Science and Technology Co., Ltd. BC-type repair materials produced were pouring process can be. 2 If the width is greater than 1mm, can use Henan Road and Bridge Department of Science and Technology Co., Ltd. of SC-type pavement repair materials processing slotting, grooving width and depth according to road class needs. If construction: Cracking a general road because cement hydration heat caused by too much, and some grading and aggregate nature, and if there is no reflection of alkali aggregate gradation is reasonable, that is cement factor and see not early strength cement, as early strength cement early hydration heat a large, easy to make concrete cracking. Processing method is to first look at the crack is not affect the structural safety, does not affect the mud pouring water on it. Must fight off the impact from the new concrete. How cement pavement crack repair Henan Road and Bridge Department can Ltd. is a professional concrete road / bridge repair production of new materials and a full range of integrated solutions and services provider, it is road repair quick passage of an industry leader! TL- 01 waterproof repair mortar has organic chemistry fine sand, coarse sand, cement, slag, silica fume and other inorganic materials, composite materials have been modified several specific synthesis of new materials for concrete repair. Excellent adhesion properties of the material has an epoxy mortar, but also has high strength, waterproof, corrosion resistance to chloride ion, easy maintenance, consistent with the expansion and contraction of concrete and other outstanding features. This project uses TL- 01 waterproof repair mortar addition after pouring concrete exterior walls of this project is not in strict accordance with the requirements of conservation. Generally expansive concrete watering curing required 7 ~ 14D, minimum 7D, after the final setting of concrete 2D to start water conservation, and expansion of the value of concrete generally 14D was basically stable. At the same time, mixed concrete expansion agent, when hydration water demand, but also to enhance the conservation than ordinary concrete, covering watering, so that the surface is always in wet conditions. Since the construction team is the first time such a high-strength concrete construction indoor concrete floor from lack of sand and construction experience, the concrete curing and did not take very effective measures to conserve facade. While the hot weather, concrete water-cement ratio control unstable; concrete vibrators in place, vibrated dense enough, it also contributed to the larger one of the reasons concrete shrinkage concrete floor dusting reasons cracks. In addition, on-site construction workers also told me: This project uses a commercial concrete, concrete slump big, little vibration appears stones sink, floating slurry, often have more bleeding, with the evaporation of water , the surface will appear plastic shrinkage cracks. There is excess water in the concrete mixture, and after the concrete induration, more prone to drying shrinkage cracks. Drag concrete floor from sand, the Department can bridge cement floor dusting can be provided by the Department of Road and Bridge Technology Co., Ltd., Henan. Net Power Technology Co., Ltd.
